Another PFAS chemical that we found in nearly every sample, including at the Capitol and EPA, is called PFHxA. It’s a large sub-set of PFAS - and while there are no bans on it in the United States, it is on the cusp of having restrictions on all of its uses in the Europe...
No, do-it-yourself test strips cannot test for PFAS. Due to their properties, PFAS require specialized equipment to detect their presence and precise levels. Test strips do not have the capability to accurately detect the presence of PFAS in a sample of water, let alone whether or not their...
Porifera, a spin out of Lawrence Livermore National Labs, has come up with a way to skirt the manufacturing problem and devise a product that leverages the unique thinness of single walled nanotubes. It has made a water filter of single walled carbon nanotubes. The tubes are packed closely to...
Assuming that some of the nitrogen in the 398 eV bonding energy state could come from N-protonated amide fragment, the increased amount that was observed for sample JK39 (see the green line in Fig. 2C, for sample JK39, it was 22% of all of the nitrogen, for HexakisaminoC60—13%) ...
I don’t know the origin of this drawing. It’s a view of both mine captain houses and the chimney, taken from the south near Audley Cove It was the most visible manifestation of the industrial past that has vanished so completely from this area. When it was built (to replace an even...
. quantified using MacConkey and M-FC media, respectively (HiMedia Labs Pvt. Ltd.). Analyses were conducted by the Wellcome Research Laboratory at CMC. Three dilutions were initially performed for TC (direct, 1:10, and 1:100) and two for FC (direct and 1:10) using a single sample for...

For the z-scan, the objective was moved by a piezo-stage (Nano F200, Mad City Labs, USA), leaving the sample at rest. This ensures that mechanical vibrations can be excluded, as it would affect drop growth and coalescence. The spatial resolution was approximately 400 nm in horizontal ...
If your freezer isn't very cold--say -10C--and you have a sample of water that will supercool to -5C before freezing starts, then the latent heat of fusion will be transferred slowly, proportional to the 5C difference. If you also have another sample of water that is crystallizing at ...
